A gallery of images of the geological past compared to the present day, taken from elsewhere on my sites.
I'll try to do others, but if you want to have a go yourself, contribute some and we'll see what they look like.
Looking from Sacred Heart across to Cofomandel range, now and 35,000 years ago.
Narrowneck area, now and 3500 years ago in sea level high (except I forgot to remove Rangitoto!)
Mt Wellington, seen from Taylor Hill, and as it might have looked while erupting in about 7000 BC. Part of Taylor Hill tuff cone in foreground.

Maungaongaonga is a hill just west of Waiotap, on the road to Waikite Springs. At the left of the photo you can see a bit sticking out of the hill, which is probably a pyroclastic debris flow. I have shown what it may have looked like as it hurtled down the hill.
